Reproduce the rename of Foot using the Xtext example in the issue and inspect the stack beginning at RefactoringCrossReferenceSerializer.getCrossRefText and DefaultReferenceUpdater.createReferenceUpdate. Trace how the JvmGenericType proxy is handled during reference updates. Done means the rename completes without the reported IllegalArgumentException for the provided example.
